Earlier quoted context omitted.
> 100%. One of the universal curses people throw at each other is implying that someone's mother is a prostitute, or that they are a product of extramarital sex, implying the promiscuity of the mother. This all is hand-in-hand with the implied comtempt towards women of course. How so? Not all women are prostitutes.
Because no one's throwing around "your father is a prostitute" as an insult.
There's all kinds of things that people insult men/fathers for that they wouldn't use for women/mothers (e.g. strength, financial success, etc). It's just gender roles, not generalized contempt for women (and going that far is probably just politically motivated exaggeration).
